About a week ago, imgur code seems to have changed. What changed was, any user, by way of a single REPORT, can remove any image from user sub from the user-sub gallery (I think posts under 10-15 minutes old or something like that). My guess is that it was to stem the tide of NSFW content. The unintended consequence is that now there are users out there that are using this “super power” to remove ANY content they want regardless of if it is appropriate for imgur. I’ve tested this with other users on other computers/browsers/IP/subnets/locations.

Don’t like a kitten? report. gone.
Don’t like how an amazing post got 20 upvotes in a minute? report. gone.
Don’t like a user? report everything they post. gone.
Don’t like a particular meme? report them all. Gone.
Don’t like firefly posts? report them all. gone.

IMHO, No single random user should have so much power with a single report. It’s being exploited to overfilter content and troll users.

Okay, so the reason is pretty evident.
You post quite sexualized contest, and it’s not very welcome in the gallery.
Potentially some people got really offended and join their efforts to report anything you post now, even if it’s not about bondage/SM/latex/gagballs anymore.

not sure if it is a bug. But it’s new. It used to take multiple reports to remove content.
Now one person can remove whatever they want.
I won’t cause it is totally dickish, but I could follow you and report anything you post on imgur so that it gets removed from the gallery. That’s the problem. One person shouldn’t have that much power.

And it is one person. Try it. I did it and posted results above. you try. report something on the first few pages that no one would report. you can remove it. I have tested this with random users that didn’t believe me at first.
